To solve for the value of x, you can simply add all of the values and expressions together and make it equal to 180 degrees, since the sum of all angles in a triangle add up to this amount.
Then we can solve for X, by algebra.
Intersecting Chord Theorem:
X = 1/2(78 + 76)
X = 1/2(154)
x = 77
25% chance or 1/4
because there are 18 total chips 9 of them are pink so 9/18 or 1/2
but she picks twice so you square it so (1/2)^2 which equals 1/4
The answer is D.
The shaded region has points less than the line and the y intercept is -4.
